When to prune alocasia sulawesi in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune alocasia sulawesi
Cut the entire petiole at the base with sterilised shears, leaving no stub. Avoid removing any leaves that still carry green colour, as partial dieback can reverse if growing conditions improve.
Alocasia Sulawesi requires minimal pruning — just remove leaves as they naturally die. This rhizomatous plant grows from a central point and cannot be shaped by cutting stems. Remove dead or yellowed leaves by severing the full petiole at the base with sterile scissors. All healthy green leaves should remain to support the plant.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
